Disclosure of Invention

The to-be-solved technical problem of the utility model is: the utility model provides a single track crane locomotive air door of colliery man-machine sharing sets up the two air doors of opening of large size in the tunnel suitable position, and upper portion stays to establish the single track recess of hanging in two air doors, guarantees that single track crane locomotive passes through, and lower part sets up door in the door in two public door leafs of air door, makes things convenient for the pedestrian current, has solved the problem of the aforesaid existence.

The technical scheme of the utility model is that: the utility model provides a single track crane locomotive air door of colliery man-machine sharing, it includes the door frame, it has public door leaf and female door leaf to articulate through hinge one symmetry in the door frame, and it has the door in the door to articulate through hinge two in the lower part of public door leaf, and the middle upper portion of public door leaf and female door leaf is fluted, is equipped with the single track in the recess.

And reinforcing rib plates are arranged on the male door leaf and the female door leaf.

The fixed plates are symmetrically arranged on two sides of the groove, movable plates capable of sliding left and right are arranged on the fixed plates, and the movable plates are symmetrically arranged on two sides of the single rail.

The utility model has the advantages that: compared with the prior art, adopt the technical scheme of the utility model, set up the two air doors of opening of large size in the tunnel suitable position, upper portion stays to establish and hangs the single track recess in two air doors, guarantee that single track loop wheel machine car passes through, lower part sets up the door in two public door leafs of air door, make things convenient for the pedestrian to pass through, when the staff needs the air door of the body of the sky, can directly draw the door in the door to pass through, when single track loop wheel machine passes through the air door, the accessible door in the door release back, open simultaneously and two pass through behind the air door. This single track loop wheel machine air door of man-machine sharing had both solved single track loop wheel machine and had used single track seamless installation, when guaranteeing that single track loop wheel machine passes through, had also guaranteed that the staff can easily open the door-in-door safely and pass through, greatly reduced must hard open the potential safety hazard when big air door, had obtained fine result of use.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings.

Example 1: as shown in attached drawings 1-2, a single track crane air door shared by coal mines and man-machines comprises a door frame 1, a public door leaf 2 and a female door leaf 3 are symmetrically hinged in the door frame 1 through a first hinge 9, a middle door 4 is hinged to the lower portion of the public door leaf 2 through a second hinge 10, a groove 5 is formed in the upper portion of the middle of the public door leaf 2 and the female door leaf 3, and a single track 6 is arranged in the groove 5. When the staff need the air door of emptiness, can directly draw the door 4 in the door to pass through, when single track crane car passes through the air door, the accessible door 4 release back in the door passes through behind the two air doors of opening simultaneously.

Furthermore, the male door leaf 2 and the female door leaf 3 are both provided with reinforcing rib plates 11.

Further, all be connected with fixed plate 8 on public door leaf 2 and the female door leaf 3, fixed plate 8 symmetrical arrangement is in the both sides of recess 5, is equipped with movable plate 7 that can the horizontal slip on fixed plate 8, and movable plate 7 symmetrical arrangement is in the both sides of single track 6.

All the parts are required to be manufactured according to the requirements of coal mine safety regulations, and the size of the door leaf can be set according to the actual mine.

Further, two back of opening the air door (being public door leaf 2 and the combination of female door leaf 3) are opened, must guarantee that the single track loop wheel machine car passes through smoothly, and two air doors must set up in groups, and the air door interval must be greater than single track loop wheel machine car total length.

Further, door 4 must set up on two public door leafs 2 of opening the air door in the door, and when door 4 closed in the door, female door leaf 3 can play certain supporting role. The door leaf lower eave is within 0.3m from the control of the height of the floor, and when people pass through, the door can be easily opened and then can pass through, so that the heavy double-opening air door is not required to be opened difficultly, and only when the monorail crane passes through, the double-opening air door is required to be opened simultaneously.

Furthermore, the groove 5 must be arranged above the middle of the double-opening air door, the height and width of the groove 5 can be determined according to the specific position of the monorail 6, and the size of the groove 5 can be adjusted by using the fixed plate 8 and the movable plate 7, so that the original ventilation system of the mine cannot be damaged. Upper portion sets up the fly leaf 7 of symmetry in the two air doors, can remove a definite position about can hanging the position according to single track 6, and the hole after the single track 6 installation uses old belt to carry out the shutoff, has both guaranteed single track 6 and has hung, can effectively control the air door again and leak the amount of wind, can not destroy the original ventilation system of mine.

Set up two air doors of jumbo size in the tunnel suitable position, upper portion stays to establish the recess 5 of hanging single track 6 in two air doors, guarantees that the single track hangs the locomotive and passes through, and lower part sets up door in the door in two public door leaves of air door, makes things convenient for the pedestrian to pass through.

The back is opened to two air doors, must guarantee that the single track loop wheel machine car passes through smoothly, and two air doors must set up in groups, and the air door interval must be greater than single track loop wheel machine car total length.

In conclusion, according to the technical scheme, the air door of the monorail crane shared by people and machines is high in practicability, seamless installation of the monorail crane using a single rail is achieved, the monorail crane is guaranteed to pass through, workers can easily and safely open the middle door of the door to pass through, potential safety hazards caused by the fact that large air doors need to be opened difficultly are greatly reduced, and when the monorail crane passes through the double-opening air doors, pressure can be relieved through the middle door of the door, and then the double-opening air doors are opened simultaneously and then the monorail crane passes through.

The parts of the present invention not described in detail are the known techniques of those skilled in the art.
